Where: Borough MarketPrice: £2.50We say: the creator of the St John’s doughnut, Justin Gellatly, has set up in Borough Market and you can’t go wrong with any of these brilliant pieces of pillowy soft dough: rhubarb and custard, caramel custard with shards of salted honeycomb, a classic raspberry jam. If there was a doughnut war, Gellatly would win.

Where: SohoPrice: £6.50We say: take a classic Italian dish served on a wipe-clean green checked tablecloth, add a pinch of 1960s Italian film posters and some table football and you’ll find yourself sitting in a retro trattoria … in central London.

Where: Smithfield or SpitalfieldsWe say: £5.70We say: it may seem like a lot to pay for a bacon buttie but this is indisputably worth every one of those 570 pennies. You get: two large chargrilled slices of proper bread from the on-site bakery, thickly buttered and liberally stuffed with Gloucester Old Spot bacon and a smear of homemade ketchup. This is otherwise known as bacon heaven.

Where: Netil Market and soon to open in SohoPrice: £3.50We say: soft steamed milk buns (AKA a “bao”) filled with soy-braised pork. They are finally getting a permanent home this year too. We. Can’t. Wait

Where: Islington, Soho or BankPrice: £3.95We say: if you thought Millionaire’s Shortbread couldn’t be improved then you would be wrong. Here, the classic shortbread is swapped for a crumbly chocolaty version, ordinary caramel for a thick wad of salted caramel, all rounded off with a layer of dark Valrhona chocolate. Well, it isn’t called "billionaire's" for nothing and it’s well worth the investment.
